A TTORNEYS Patented Feb. 3, 1931 UNITED STATES PATENT OFFICE WILLIAM C.BRUMDER, OF MILWAUKEE, WISCONSIN; THEKLA U. BRUMDER EXECU- TRIX OF SAIDWILLIAM C. BRUMDER, DECEASED EXERGISING DEVICE Application filed June 7,1928. Serial No. 283,563.

This invention relates to improvements in an exercising device.

It is one of the objects of this invention to provide an exercisingdevice embodying a mechanical movement which is particularly adapted foruse in exercising and massaging machines, wherein the peculiar and novelmovement is imparted to a body engaging member, the latter beingefficacious in stimulating muscular activity, thereby correcting manydisorders which result from sedentary habits of living.

It is a further object of this invention to provide an expercisingdevice embodying a mechanical movement which is transmitted to a saddleof the exercising machine to exercise the hip and back muscles of theuser and to benefit the body generally.

It is a further object of this invention to provide an exercising devicewhich may be used in connection with a massaging member, the latterstimulating the flow of blood in the portion of the body to which it isapplied.

It is a further object of this invention to provide an improvedexercising device which is simple in construction and well adapted forthe purpose described.

With the above and other objects in view the invention consists of theimproved exercising device and all its parts and combinations as setforth in the claims and all equivalents thereof.

In the accompanying drawing in which the same reference charactersdesignate the same parts in all of the views:

Fig. 1 is a side elevation of an exercising device embodying theimproved mechanical movement, parts being broken away and parts beingshown in section;

Fig. 2 is a plan view thereof;

Fig. 3 is a front elevation; and

Fig. 4 is a section taken on line 4:-4: of Fig. 1.

Referring to the drawing, the numeral 5 designates a base member, uponwhich is mounted a frame 6. The latter comprises an I-shaped frame base7, an L-shaped standard 8, and a vertically extending bearing portion 9,the latter being connected to the upper end of the standard. The framebase 7 is secured to the base member 5 by screws 10.

Journaled within the bearing 9 is a shaft 11. A cam disk 12 is rigidlymounted on the upper end of the shaft at an angle oblique to the axis ofsaid shaft. The disk 12 is1r0tatably received in an annular recess 13 ina saddle or movable member 14, the recess being closed by a plate 15having a central opening 16 through which the shaft 11 extends. A pin orextension 17 projects'downwardly from the plate 15, its lower end beingreceived by a slot 18 in a frame extension 19. The saddle is revolubleindependently around the plate 15 to permit its being swung to variouspositions.

The lower end of the shaft 11 has a pulley 20 rigidly secured thereto,the latter being connected by an endless belt 21 to a pulley 22 on thedrive shaft of an electric motor 23. The motor is wired to a rheostat 24which is controlled by a foot pedal 25. A wire 26,

provided with a plug 27 for insertion in an ordinary house socket,extends from the rheostat.

The operationand use of the device is as follows: The plug 27 isinserted in an electric socket, and the user mounts the saddle andplaces his foot upon the pedal 25. The latter closes the circuit to theelectric motor and at the same time, through the rheostat 24, regulatesthe speed of the motor. By means of the pulleys 20 and 22'and theendless belt 21, the shaft '11 is rotated. As the shaft turns, the camdisk 12, mounted at an oblique angle on its upper end, causes the saddleto wabble, the movement being in a circumferential path, as indicated bythe dotted lines in the drawing. The pin 17 moves back and forth in theslot 18, allow ing the saddle to wabble but preventing its rotation withthe cam disk 12. V This peculiar movement of the saddle is veryeffective in exercising the muscles of the user.

By a slight modification, the device may be mounted in a position atright angles to that shown, and a massaging membermay be substituted forthe saddle When the device is thus equipped, the user stands against themassaging member, and the latter, by its (ill peculiar movement, willthoroughly massage the body.

It is not desired to limit the scope of this invention to the particulartype shown and described, as the broad concept of the inventioncontemplates all changes and modifications as may come within the scopeof the claims.

From the foregoing description, it may be seen that the improvedexercising device is simple in construction and operation, and welladapted for the purpose described.

What I claim is:

1. An exercising device comprising .a frame, a rotatable membervertically mounted in-said frame a disk rigidly mountedion one end ofsaidrotatable member at anangleoblique to the axis thereof, .a movablehorizontally positioned saddleflmember engaged by saidldisk, the latter,when rotated, imparting .a wabbling movement to the movable saddlemember, and means for preventing rotation of-the movable saddle memberwith thedisk.

2. An exercising device comprising a frame, a rotatable membervertically mounted .in said frame, a disk rigidly mounted on one end ofsaid rotatable member at an angle oblique to the axis thereof, a movablehorizontally positioned saddle member having an annular recess therein,said disk being revoluble within the annular recess to impart a wabblingmovement .to the .movable saddle member, and means for preventingrotation of the movable saddlemember with the disk.

3. An exercising device comprising a frame having a slotted extensioninconnection therewith, a vertically extending bear- ;ing member carried.by said frame, a shaft journaled in said bearing, a disk rigidlymounted on one end of said shaft at an angle oblique to the axisthereof, a movable horizontally positioned saddlemember having. an

annular recess therein, said disk being revoluble within said annularrecess to impart a wabbling movementto the movable saddle-member,.and.anextension in connection with the movable saddle memberand engaging the slotted extension of the frame, said extension beingmovable back and forth in the slot to permit the 'wabbling of themovable saddle member, but preventing rotation thereof with the disk.

4. An exercising device comprising a frame having a slotted extension inconnection therewith, a vertically extending :bearing ,member carried bysaid frame, a shaft journaled in said bearing, .a disk rigidly mountedonone end of said shaft at an angle oblique to-the axis thereof, .amovable saddle .member having an annular recess therein, -sa1dd1skbe1ngrevoluble w thin said annular .recess to imparta wabbling movement tothe movable saddle member, a .plate, having a central opening for theshaft, securedto-the movable saddle member to maintain the disk Withinthe recess, and an extension in connection with the movable saddlemember and engaging the slotted extension of the frame, saidextension'being movable back and forth in the slot to permit thewabbling of the movablesaddle member but preventing rotation thereofwith thedisk.

5. An exercising device comprising a rotatable member, a saddle,connecting means between said rotatable member and sa which will impart.a wa bling movement to the saddle when the rotatable member is rotated,means for preventing rotation of the saddle with the rotatable member,and an electric motor for operating said rotatable member.

6. An exercising machine comprising a frame, a bearing member carried bysaid frame, aslotted extension in connection with said bearing member, ashaft journaled in the bearing, a disk rigidly mounted on one end ,ofthe shaft at an angle oblique to the axis thereof, a saddle having anannular recess therein, the disk being revoluble within said recess toimpart a wa'bbling movement to the saddle,means for maintaining saiddisk within the recess, a pin in connect1on With the saddle and engagingthe slotted e xtension of the bearing, said pin being movable back andforth in the slot to permit the wabbling movement of the saddle butpreventing rotation thereof with the disk, an electric motor foroperating said rotatable member, and .control means for the motoroperable from a position on the saddle.

In testimony whereof, I aliix my signature.
